Opinion:
An absolutely brilliant and disturbing book at the same time. Very up to date and realistic. One thinks all the time, it's just a matter of the same, when the contents are true. The writing style is fluid, exciting and thrilling. There is an excellent end and despite previously announced sequel, the story is coherent and plausible in itself. The characters are described in detail and the psychological mechanisms of action very well understood. It should be noted perhaps are the many technical terms that will surely understand not everyone. But even if not, the book is exciting and makes what has been said more realistic.
Cover and title:
The cover illustrates for me excellently the whirlpool, or is being drawn on the internet. Can the experts the code number 0 and 1, based on each programming, immediately recognize. Evil is certainly circumscribed well with Deamon.
Conclusion:
Realistic and therefore also very scary. A book that transferred the balance of power in today's society very into question. When one thinks of the CIA, the FBI, or SEK. A brilliant idea and the cyber thriller par. One can probably anxiously waiting to continuing Darknet. Highly Recommended. From me, there are five stars.
